The best product if you have irritated scalp. A bit on the pricy side but works better than any medication I've tried.

I simply adore it as I suffer from very sensitive and itchy scalp. It does wonders for hair too but I mostly use it as a scalp relief as it's much more effective as any medication has been. It's expensive as a mask but not as a medication!

My experience with this product comes from leaving it on for various lengths of time: the recommended 20 minutes, an hour, a few hours and overnight. My hair is in good condition; not colour treated and I rarely use heat styling (bar blow drying). I feel I benefit the most from leaving it on overnight or for a few hours (I.e. put on in the morning for an evening event). It leaves my hair extremely soft, weightless and shiny. I just finished a tube of it, and own another brand new tube, but already I want to but another to allow for frequent use! I do shampoo my hair prior and on occasion condition (both ESPA) also before leaving on, and repeating after. 

I only use this every so often as I have, for the most part, unproblematic straight and fine hair. I usually wet my hair and wash my body in the shower beforehand, and wash my hair if I feel the need, say if I’ve left my hair for a few days. I don’t like leaving hair masks in overnight so use it using the day and leave it on for at least an hour or so. I follow it with ESPAS bergamot and jasmine shampoo and conditioner. After blow drying with heat protection spray, my hair feels so light and shiny! I’m obsessed. I’ve ordered another tube to use more regularly.
